7 Claims.

This invention relates to an emergencystimulator unit of the hand portable, holding and positioning type for the administering of oxygen and oxygen in conjunction with carbon dioxide, and

it is intended to be placed in rst aid stations, police and fire departments for use in ambulances and patrol cars, industrial plants, in hospital Wards for the use of the staff, in physicians oiiices or at any other suitable desired places.

The application of oxygen or oxygen in conjunction with carbon dioxide for stimulation is Valuable in many cases, shock and hysterics, gassing of al1 kinds, heart attacks, loss of blood, drowning cases, attempts at suicide, use of narcotics, intoxication and many others, and the aim of this invention is to provide, a stimulator unit acting to temporarily aid the patient until he may be brought under the care of a physician. The unit in accordance with this invention is not intended for articial resuscitation or to inspire breathing but to articially stimulate the patient by the administering of oxygen or oxygen in conjunction With carbon dioxide.

The devices as now available commercially for the administration of oxygen and oxygen in conjunction with carbon dioxide are difficult to handle, carry and operate. This invention aims to provide, in a manner as hereinafter set forth,

a unit of the class referred to which will overcome the objections as aforesaid and which is extremely portable, conveniently handled, simple to operate, immediately available for use, possessing greater applicatory variation, compact, strong, durable, and thoroughly eiiicient in its use.

With the foregoing and other objects in View, the invention consists of the novel construction, combination and arrangement of parts as will be more specically referred to and are as illustrated in the accompanying drawing wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawing:

Figure 1 is a side elevation of the unit,

Figure 2 is a section on line 2 2, Figure l,

Figure 3 is a section on line 3 3, Figure 1,

Figure 4 is a front elevation of the mask or inhaler,

Figure 5 is a section on line 5 5, Figure 1, and

Figure 6 is a section on line 6 6, Figure 3.

The unit includes a container or tank of the desired capacity for oxygen or for oxygen in conjunction with carbon dioxide. The tank or con- 55 tainer I is provided with a neck 2 which is inte- (Cl. 12S-203) riorly threaded, and extending into and threadedly engaging with the neck 2, as well as extending upwardly from the latter is a peripherally threaded nipple 3. Encompassing the nipple 3 and extending upwardly therefrom is a valve casing i consisting of a tubular housing 5 formed at its upper end with an inwardly extending annular ange 5 having its edge threaded. The housing 5 in proximity to its lower end and on its inner face is formed with a valve seat 1. The intake for housing 5 is indicated at 8. The body of housing 5 is formed intermediate its ends with an opening 9 constituting an outlet. There is associated with the housing 5 a shut-off valve structure for the container or tank I. The valve structure includes a valve IE] carried on the inner end of the threaded stem II. The latter threadedly engages with the flange 6. The outer end of stem II is provided with a handle I2. The valve IE! is for coaction with the seat 1 for controlling the discharge from a container or tank I. Encompassing the housing 5 is a collar I3 formed with a pair of inner endwise aligned openings It, I5 disposed diametrically thereof. The periphery of collar I3 is provided with a pair of annular bosses I6, I1. The boss I6 is of greater inner diameter than the diameter of opening I4 and the boss I6 is arranged at the outer end of opening I4. The collar I3 is formed with a shoulder I8 at the outer end of opening I4. The inner diameter of the boss I1 is the same as the diameter of the opening I5. The inner face of the boss i1 forms a continuation of the wall of opening I5. The wall of opening I5 and the inner face of boss I1 are threaded. Extending through the boss I1 and opening I5 and abutting the housing I5 is a binding screw I9 which acts to secure the collar I3 stationary to the housing 5. The opening 9 in housing 5 registers with the opening I4 in collar I3. The boss I6 is interiorly threaded and extending into boss I6, abutting shoulder I8 and threadedly engaging with boss I6 is a conducting-off pipe 20.

The unit includes a pressure regulator 2l into which the pipe opens. Arranged over the pressure regulator 2|, as well as communicating with the latter is a pressure gauge 22. The unit includes an inhaler or mask 23 having an intake opening 24 and an expiratory valve 25. Formed integral with the mask 23 and registering with the opening 24 is an intake pipe 25 formed of a horizontal leg 21 and a vertical leg 28. The leg 28 extends upwardly from the leg 21 adjacent the inner end of the latter. The leg 28 is of less diameter than the leg 21.

Leading from the pressure regulator 2I is a seclower ends of the body part 33.

tional supply pipe 29 for the intake pipe 26. The supply pipe 29 consists of a rigid section 33 Which is connected with the pressure regulator 2i and a flexible tubular section 3i which couples the section 3@ with the leg 28 of the intake pipe 26. The diameter of section 3@ of supply pipe 29 is the same as the diameter of the leg 28 of the intake pipe 26. The section 3l encompasses the lower end of section 3U and the upper Vend of leg 28. The section 3l is short but-greater in length than the section 30 and regulator 2l. The section 3i is in the form of a rubber tube.

The container or tank l is provided with a handle structure 32 for conveniently handling, carrying and positioning the unit. The structure 32 consists of a segmental-shaped bo-dy part 33 having extended outwardly from its upper and lower ends parallel arms 3e, 35 between which is arranged a handle piece 36. The latter is connected to the outer ends of the arms 34, 35 by the holdfast means 35a. The arms 34, 35 are disposedV centrally with respect to the upper and The sides of body part 33 have extending therefrom a pair of Voppositely disposedv substantially semi-circular straps 37, 38 having their free ends formed with tongues 39, tu respectively. The tongues are arranged in parallel relation and are apertured. The straps 31, 38 are positioned against the container or tank I and are maintained in binding engagement therewith by an adjustable clamping device 4l carried by the tongues39, d0.
